Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a sputum suction waste processor for use with a ventilator and its method of use, for dealing with problems such as sputum splashing, secretion overflow, and spread of pathogenic microorganisms during sputum suction. Background Technology

[0002] In clinical respiratory support therapy, patients with endotracheal intubation or tracheotomy often require mechanical ventilation and suctioning when necessary. Currently, two methods are commonly used for suctioning: if the patient is critically ill and in a state of severe hypoxia, it is not advisable to completely wean them off the ventilator; in this case, the procedure is usually performed by opening the cap on the closed suction catheter of the ventilator pre-advanced catheter. If the patient's condition permits, the ventilator pre-advanced catheter can be temporarily completely disconnected from the artificial airway. However, in both of these procedures, due to the sudden change in intrathoracic pressure, sputum or secretions in the patient's airway are easily expelled with the airflow. At the same time, secretions remaining inside the ventilator pre-advanced catheter and pathogenic microorganisms exhaled by the patient will also spread, causing contamination of the patient's bed, clothing, walls, and even the air in the ward, increasing the risk of cross-infection and the burden of environmental cleaning.

[0003] It is worth noting that a systematic solution for effectively addressing the aforementioned problems has not yet been developed in clinical practice. In particular, there is a lack of integrated, efficient, and safe dedicated devices or methods for handling sputum splashing, secretion overflow, and the spread and contamination of exhaled pathogenic microorganisms. Existing technologies primarily focus on the simple suctioning procedure itself, without comprehensively considering the accompanying contamination control issues, reflecting a significant gap in this technological direction.

[0004] More profoundly, the fact that this problem has long been neglected or not effectively resolved indicates that it has not been a key area for improvement in the general understanding of those skilled in the art. Conventional approaches in the industry focus on the efficiency of suctioning procedures or the continuity of patient ventilation, while neglecting the secondary contamination and infection control deficiencies that arise during the procedure. Therefore, providing an integrated solution that can effectively manage sputum splashing, secretion overflow, and the spread of pathogenic microorganisms is indeed one of the important areas for improvement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a sputum suction waste processor and its usage method that is compatible with a ventilator, so as to solve the problems of sputum splashing, secretion overflow and spread of pathogenic microorganisms, avoid secondary pollution and infection caused during sputum suction operation, and be easy to operate.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A waste disposal unit for suctioning, used in conjunction with a ventilator, includes: a fixing component and a waste disposal component;

[0008] The fixing component includes a clamping part and two retractable cables connected to the clamping part;

[0009] The waste treatment assembly includes a first container and a second container, which are detachably connected to two spiral cables respectively.

[0010] The first container is provided with a first interface, a suction port and a first waste washing outlet. When suctioning is performed without disconnecting the ventilator, the first interface is a connection to the artificial airway; when suctioning is performed without disconnecting the ventilator, the first interface is a connection to the closed suction tube on the ventilator pre-intubation tube.

[0011] The second container is provided with a ventilator pre-advanced catheter terminal fixing interface and a second waste flushing outlet; the ventilator pre-advanced catheter terminal fixing interface is provided with a U-shaped slot for aligning the ventilator pre-advanced catheter with the fixing interface and locking it in place.

[0012] Both the first and second waste flushing outlets are equipped with sealing caps.

[0013] As a further improvement of the present invention, the clamping part is a ventilator bracket fixing clip or a bed rail fixing clip.

[0014] Furthermore, the retractable cable is a spiral cable.

[0015] Furthermore, the first container and the second container are containers with streamlined internal cavities and smooth inner walls.

[0016] Furthermore, on the first container, the first interface is positioned opposite to the suction port, the first waste flushing outlet is located at the bottom of the container between the two, and the top of the container is a retractable cable connection end; on the second container, the ventilator pre-catheter terminal fixing interface is located on one side wall of the second container, the second waste flushing outlet is located at the bottom of the container, and the top of the container is a retractable cable connection end.

[0017] Furthermore, the first interface is a flexible, outwardly expanding structure, with the outer diameter being larger than the inner diameter, and is used to connect to the artificial airway opening and the connection port on the closed suction tube of the ventilator pre-conduit.

[0018] Furthermore, the suction port on the first container adopts a cross-shaped seal;

[0019] And / or, a disinfectant tablet is placed inside the sealing cap of the first waste flushing outlet and the second waste flushing outlet respectively.

[0020] Furthermore, the contaminant is sputum, other secretions besides sputum, and / or pathogenic microorganisms.

[0021] The present invention also provides a method of using the above-mentioned sputum suction waste processor for use with a ventilator, including two methods: suctioning without disconnecting the ventilator and suctioning without disconnecting the ventilator.

[0022] When weaning off the ventilator for suctioning, including:

[0023] (1) Fixation: Clamp the clamping part of the fixation component to the ventilator bracket or bed rail, ensuring that the container is detached from the bed surface and within the operable range;

[0024] (2) Connection: Disconnect the ventilator pre-container tube from the artificial airway, exposing the artificial airway opening and the end of the ventilator pre-container tube; seal the first interface of the first container with the artificial airway opening, and the first container receives the waste sprayed into the artificial airway; snap the end of the ventilator pre-container tube into the ventilator pre-container tube end fixing interface of the second container, and the second container receives the waste flowing out of the end of the ventilator pre-container tube.

[0025] (3) Suctioning: If suctioning is required, suctioning is performed through the suction port on the first container;

[0026] (4) Waste disposal: After suctioning, separate the first interface of the first container and the retractable cable from the first container, rinse the first container, and the waste will flow out from the first waste rinsing outlet; separate the second container from the end of the ventilator pre-catheter and the retractable cable from the second container, rinse the second container, and the waste will flow out from the second waste rinsing outlet; or directly remove the clamping part and directly rinse the first container and the second container.

[0027] When suctioning without weaning off the ventilator, including:

[0028] (1) Fixation: Clamp the clamping part of the fixation component to the ventilator bracket or bed rail, ensuring that the container is detached from the bed surface and within the operable range;

[0029] (2) Connection: Open the sealing cap on the closed suction tube on the ventilator pre-catheter to expose the connection port, and seal the first interface of the first container with the connection port; the first container receives the sprayed waste;

[0030] (3) Suctioning: If suctioning is required, suctioning is performed through the suction port on the first container;

[0031] (4) Waste disposal: After suctioning, separate the first interface of the first container and separate the retractable cable from the first container, rinse the first container, and the waste flows out from the first waste rinsing outlet or directly remove the clamping part and rinse the first container directly.

[0032] Furthermore, a disinfectant tablet is placed inside the sealing cap of the first and second waste flushing outlets. During waste treatment, clean water is poured in to mix the disinfectant tablet with the clean water at the flushing outlet, thereby disinfecting the inner wall of the container.

[0033] By adopting the above technical solution, the present invention has at least the following advantages:

[0034] (1) The sputum suction waste processor of the present invention, which is used in conjunction with a ventilator, adopts a combination of a fixing component (clamping part and two retractable cables connected to the clamping part) and a waste treatment component (first container and second container). The fixing component is convenient for clamping and fixing, and the retractable cables allow the containers to move freely within the operable range. The first container and the second container are detachably connected to two spiral cables, which makes it convenient to disassemble the first container and the second container for waste cleaning. The first container has three ports and the second container has two ports. The combination of the two makes it suitable for sputum suction without or without disconnecting the ventilator. Regardless of the method used, the waste can be effectively treated.

[0035] (2) The sputum suction waste processor of the present invention fills the gap in the medical field in this technical direction, and effectively solves the problems that have long been neglected in this field, such as sputum splashing, secretion overflow and pathogenic microorganism spread, avoids secondary pollution and infection caused during sputum suction operation, and is easy to operate, while improving the satisfaction rate of medical staff and family members. Attached Figure Description

[0036] The above is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Figure 1 This is a schematic diagram of the structure of a sputum suction waste processor used in conjunction with a ventilator according to one embodiment of the present invention;

[0038] In the diagram: 1-Clamping part; 2-Retractable cable; 3-First container; 31-First interface; 32-Suction port; 33-First waste flushing outlet; 4-Second container; 41-Ventilator pre-advanced catheter terminal fixing interface; 42-U-shaped slot; 43-Second waste flushing outlet. Detailed Implementation

[0039] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that a more thorough understanding of the invention will be achieved and that the full scope of the invention will be conveyed to those skilled in the art.

[0040] like Figure 1 As shown, this embodiment provides a sputum suction waste processor for use with a ventilator, including: a fixing component and a waste processing component; the fixing component includes a clamping part 1 and two retractable cables 2 connected to the clamping part 1; the clamping part 1 has a clamping and fixing function, using a ventilator bracket clamp or a bed rail clamp, and has a certain clamping force to adapt to different clamping positions; in use, the clamping part 1 can be clamped onto the ventilator bracket or bed rail to ensure that the container is detached from the bed surface and within the operable range. The retractable cables 2 have a telescopic length adjustment function, and are preferably spiral cables.

[0041] The waste treatment assembly includes a first container 3 and a second container 4.

[0042] The first container 3 is provided with a first interface 31, a suction port 32, and a first waste flushing outlet 33. When suctioning is performed without disconnecting the ventilator, the first interface 31 is used to connect to the artificial airway, connecting to the artificial airway opening at the patient's end. When suctioning is performed without disconnecting the ventilator, the first interface 31 is used to connect to the closed suction catheter interface on the ventilator's pre-tracheal tube, connecting to the closed suction catheter connection port on the ventilator's pre-tracheal tube (the small cap on it needs to be opened). Due to the difference in diameter between the two, as a preferred design, the first interface 31 has a flexible, outwardly expanding structure, with the outer diameter larger than the inner diameter. In use, the larger outer diameter is used to connect to the artificial airway opening, while the smaller inner diameter is used to connect to the closed suction catheter connection port on the ventilator's pre-tracheal tube. The flexible design also ensures a tight seal. As can be seen from the above, the first container 3 is used in both suctioning methods. The suction port 32 is the suction operation entrance, used to connect with the suction component for suctioning. Preferably, the suction port 32 adopts a cross-shaped sealing opening to facilitate the insertion and sealing of the suction component. The first waste rinsing outlet 33 is provided with a sealing cover, and a disinfection tablet is stored inside the sealing cover.

[0043] Preferably, in the layout of the first container 3, the first interface 31 is arranged opposite to the suction port 32, the first waste flushing outlet 33 is located at the bottom of the container between the two, and the top of the container is the connection end of the retractable cable 2.

[0044] The second container 4 is provided with a ventilator pre-advanced catheter end fixing interface 41 and a second waste flushing outlet 43; a U-shaped slot 42 is provided at the ventilator pre-advanced catheter end fixing interface 41 for aligning the ventilator pre-advanced catheter with the fixing interface and locking it in place; the opening of the U-shaped slot 42 faces upward, and the depth and width of the slot are adapted to the diameter of a conventional ventilator pre-advanced catheter; in addition, a sealing cap is also provided on the second waste flushing outlet 43.

[0045] Preferably, in the layout of the second container 4, the ventilator pre-advanced catheter terminal fixing interface 41 is located on one side wall of the second container 4, the second waste flushing outlet 43 is located at the bottom of the container, and the top of the container is the connection end of the retractable cable 2. Here, the second container 4 is only used to connect with the ventilator pre-advanced catheter terminal when the ventilator is disconnected for suctioning.

[0046] The first container 3 and the second container 4 are detachably connected to two spiral cables 2. The spiral cables 2 allow the first container 3 and the second container 4 to move freely within the operable range. The detachable connection makes it easy to disassemble the first container 3 and the second container 4 for cleaning.

[0047] In terms of materials, the first container 3 and the second container 4 are containers with streamlined inner cavities and smooth inner walls, such as medical-grade plastic, which facilitates the collection and rinsing of waste, avoids waste residue, and can be reused.

[0048] The aforementioned contaminants include sputum, other secretions besides sputum, and / or pathogenic microorganisms.

[0049] The aforementioned sputum suction processor for use with the ventilator has two usage modes: one is to remove the ventilator for suctioning, where the patient's condition allows for a brief removal from the ventilator and the waste needs to be quickly disposed of; the other is to keep the ventilator on for suctioning, where the patient needs to maintain ventilator ventilation and not interrupt breathing.

[0050] When weaning off the ventilator for suctioning, the following methods of use are included:

[0051] (1) Fixation: Clamp the clamping part 1 of the fixing component to the ventilator bracket or the bed rail, ensuring that the container is detached from the bed surface and within the operable range;

[0052] (2) Connection: Disconnect the ventilator pre-container tube from the artificial airway, exposing the artificial airway opening and the end of the ventilator pre-container tube; seal the first interface 31 of the first container 3 with the artificial airway opening, and the first container 3 receives the waste sprayed into the artificial airway; snap the end of the ventilator pre-container tube into the ventilator pre-container tube end fixing interface 41 of the second container 4, and the second container receives the waste flowing out of the end of the ventilator pre-container tube.

[0053] (3) Suctioning: If suctioning is required, suctioning is performed through the suction port 32 on the first container 3;

[0054] (4) Waste disposal: After suctioning, separate the first interface 31 of the first container 3 and separate the retractable cable 2 from the first container 3, rinse the first container 3, and the waste flows out from the first waste rinsing outlet 33; separate the second container 4 from the end of the ventilator pre-catheter and separate the retractable cable 2 from the second container 4, rinse the second container 4, and the waste flows out from the second waste rinsing outlet 43; or you can directly remove the clamping part 1 and directly rinse the first container 3 and the second container 4.

[0055] When handling waste, pour in clean water to mix the disinfectant tablets at the rinsing outlet with the water, thus disinfecting the inner wall of the container.

[0056] When suctioning without disconnecting from the ventilator, the following methods of use are included:

[0057] (1) Fixation: Clamp the clamping part 1 of the fixing component to the ventilator bracket or the bed rail, ensuring that the container is detached from the bed surface and within the operable range;

[0058] (2) Connection: Open the sealing cap on the closed suction tube on the ventilator pre-catheter to expose the connection port, and seal the first interface 31 of the first container 3 with the connection port; the first container 3 receives the sprayed waste;

[0059] (3) Suctioning: If suctioning is required, suctioning is performed through the suction port 32 on the first container 3;

[0060] (4) Waste disposal: After suctioning, separate the first interface 31 of the first container 3 and separate the retractable cable 2 from the first container 3, rinse the first container 3, and the waste flows out from the first waste rinsing outlet 33; or you can directly remove the clamping part 1 and rinse the first container 3 directly.

[0061] When handling waste, pour in clean water to mix the disinfectant tablets at the rinsing outlet with the water, thus disinfecting the inner wall of the container.

[0062] In summary, the sputum suction waste processor of the present invention fills a gap in the medical field in this technological direction, effectively solving problems that have long been neglected in this field, such as sputum splashing, secretion overflow, and the spread of pathogenic microorganisms. It avoids secondary pollution and infection caused during sputum suction, is easy to operate, and improves the satisfaction rate of medical staff and their families.
